Mercedes’ last supercar still packs a mean punch

Mercedes ended production for the SLS-AMG in 2014 after bursting into the scene as the first-ever stand-alone model that AMG built. During its run, the SLS AMG also became a favorite among aftermarket tuners. Even to this day, two years after production for the supercar stopped, tuners are still creating programs for the beloved supercar. Tag Motorsports counts itself in this group as it recently unveiled its tuning kit for the 2013 SLS AMG Roadster that results in an output of 620 horsepower and 522 pound-feet of torque.

The modifications to the car’s 6.3-liter V-8 engine aren’t the only upgrades included in Tag Motorsports’ tuning kit. It also comes with a cosmetic package, suspension upgrades, and of course, a new set of wheels. The subtle improvements to the SLS AMG’s looks and chassis create a more purposeful look for the car while also enhancing its performance and handling capabilities.

Sure, the SLS AMG is no longer being built, but those who lucky enough to own one of these bad boys will now have the opportunity to give their supercars a modern tuning kit that can once again bring out the ultimate expression of what the SLS AMG was, and continues to be.

Tag Motorsports resisted on making any drastic modifications to the exterior of the SLS AMG Roadster, opting instead to fit it with a black-out cosmetic package and clear paint protection from XPel. The result doesn’t show itself at first glance, but it becomes more visible as time passes. In addition to the package and paint protection, the tuner also added a new set of 20- and 21-inch, polished matte brown-finished ADV5.0 MV2CS wheels from ADV.1 wheels.

Interior

There are no upgrades given to the SLS AMG Roadster’s interior

Added power and improved performance are the real highlights of Tag Motorsports’ program for the SLS Roadster. For this, the tuner used RENNtech’s R2 performance kit, which is made up of an ECU upgrade, stainless steel long tube headers with 200-cell cats, and an X-Pipe. The results won’t blow anybody away, although it’s still good enough to bring the SLS Roadster’s output to 620 horsepower and 522 pound-feet of torque.

Performance numbers weren’t mentioned, but with the standard model capable of sprinting from 0 to 60 mph in 3.5 seconds to go with a top speed of 192 mph, it’s reasonable to think that the R2 performance kit can shave that 60-mph sprint time to about 3.3 seconds and increase the top speed to about 200 mph.

Chassis and Suspension

The extra power should be felt by the SLS Roadster’s chassis and suspension so Tag Motorsports addressed that by fitting the SLS with H&R lowering springs.

Pricing

The California-based tuner didn’t announce pricing for the program, and given the combination of modifications from different sources, those interested in the kit are better off contacting the tuner directly to get a price quote.

The Mercedes SLS-AMG Roadster is “outdated” if you compare it today’s sports cars and supercars. But with this tuning program from Tag Motorsports, the SLS Roadster has the tools to make for a compelling match-up against the new Porsche 911 Turbo S. The numbers are close together with the 911 Turbo S packing 580 horsepower out of its 3.8-liter boxer-six engine. That’s good enough to propel the 911 Turbo S from stopped to 60 mph in 2.9 seconds to go with a top speed of 198 mph. Both cars should have some advantages over the other, which would make it a pretty compelling match-up.

You have to appreciate a tuner like Tag Motorsports for not disregarding the previous generation performance cars just because something new and better has arrived. It’s nice to see that a car like the SLS Roadster can still get some aftermarket love, even though it has since been replaced, at least in Mercedes’ pecking order, by the AMG GT. It just goes to show that love for the SLS Roadster runs deep and despite not being in production anymore, there are tuners that still want to see the car compete against today’s crop of performance cars.
